Homemade front torque boxes

Thanks for the replys. I picked up some urethane seam sealer tonight. I plan on sealing the underside of the car at the joints. I will post when it is done. A good seam sealer works to seal, but is also a flexible adhesive. Andrew
why put the chamfer up ? looks like it will try to hold a little water if u seal the seams. Think I would have turned them down for drainage.
